Functional Description
The ’AC378 consists of six edge-triggered D-type flip-flops
with individual D inputs and Q inputs. The Clock (CP) and
Enable (E) inputs are common to all flip-flops.
When the E input is LOW, new data is entered into the
register on the LOW-to-HIGH transition of the CP input.
When the E input is HIGH the register will retain the present
data independent of the CP input.
